工程施工平行发包应根据______确定发包合同范围。

A．便于编制项目WBS的原则

B．建设项目施工的不同专业系统

C．参与施工投标的单位数量

D．项目分解结构

E．参与施工投标单位的性质和特点

答案

参考答案：B,D,E

解析：本题考核的是工程施工平行发包合同范围的确定。在施工平行发包模式中，业主将不同的施工任务分别委托给不同的施工单位，各个施工单位分别与业主签订合同，各个施工单位之间没有合同关系和指令关系。采用施工平行发包模式，通常在该部分工程的施工图完成后才进行发包，有利于采用总价合同形式。对施工任务的平行发包，发包方可以根据建设项目的单项工程进行分解发包，也可以根据建设项目的单位工程甚至分部工程(如不同的专业系统)进行分解发包。
